[Optimization of a recording procedure of a multifocal electroretinogram].

The paper presents a procedure and conditions for recording multifocal electroretinogram (mfERG), its origin, and factors influencing small-signal ERG. The optimal conditions of ERG extraction using the existing method are appraised and indications for its use in ophthalmological care defined. The results of comparing the new types of electrodes developed in Russia for ERG recording and a DTL electrode included in the ISCEV guidelines are presented.
